Document Description
Project will reconfigure the SR 4 eastbound and westbound off-ramps at Bailey Road and improve access for pedestrians and bicyclists along Bailey Road (Figure 3). Specifically, the project will include the removal of the westbound loop off-ramp and underlying pedestrian tunnel on the northwest side of the interchange. A temporary platform will be installed underneath the loop off-ramp structure during demolition to protect the underlying Contra Costa Canal. The westbound diagonal off-ramp on the northeast side of the interchange will be widened to two lanes for retaining wall will be constructed along the north side of the ramp which will require excavation of an area approx. 6 feet wide and 6 feet in depth. The project will remove the free right turns at the eastbound SR4 loop off ramp as well as the BART access road. The intersection and traffic signal will be modified to control the right turn movements. A 12-foot wide sidewalk along the southbound side of Bailey Road and a 6 foot wide sidewalk along the northbound side will be constructed through the interchange area as well as Class 2 bike lanes. The project will result in removal of approx. 22,500 sq. ft. (0.5 acre) of pavement and install approx. 9,400 sq. ft. of pavement. Replacement planting/landscaping will be installed as needed. The project will maintain the existing drainage pattern and impacted drainage inlets will be modified. Temporary construction easements may be needed for construction staging which will occur in already disturbed areas. Utility relocations will be required. A minimum of one lane will be open during construction activities. Emergency vehicles will have access at all times.
